2.5V threshold supervisor — active-low open-drain
The TPS389025DSET: The output is open-drain, active-low — the pin pulls low on a fault and releases to high-impedance when the supply recovers. This suits wired-OR reset sharing across multiple ICs on a board.
Temperature range and package — industrial deployment
An outdoor telecom or factory-floor controller that sees 85°C ambient still has margin to the upper limit. Housed in a 6-WSON (1.5x1.5 mm) package — the 0.5 mm pitch and exposed thermal pad demand a soldering profile consistent with JEDEC MSL-1 moisture sensitivity. The small footprint fits dense mixed-signal PCBs where board space is tight.
ROHS3 compliant per. The base product number TPS389025 covers the family; the DSET suffix identifies the tape-and-reel package option.
